Previous issue date: 2016-06-09 / Este trabalho tem como objetivo analisar ind?cios de conhecimentos matem?ticos, impl?citos nas opera??es comerciais de tr?s feirantes da feira livre localizada no Conjunto Habitacional de Nova Natal em Natal/RN. Para alcan?ar tal objetivo, buscou-se apoio nas concep??es de D?Ambrosio (2002) sobre Etnomatem?tica, nas propostas dos documentos oficiais, al?m da pesquisa qualitativa. Na parte emp?rica, usou-se procedimentos da Etnografia, como o di?rio de campo, a entrevista semiestruturada e a observa??o participante. A partir das an?lises dos dados coletados, elaborou-se um Caderno de Atividades como proposta para subsidiar o processo de ensino?aprendizagem em Matem?tica, norteada pelos pressupostos da Metodologia de ensino?aprendizagem?avalia??o atrav?s da Resolu??o de Problemas, nas concep??es de Allevato e Onuchic (2009) que auxiliaram na constitui??o do Produto Educacional ao n?vel da Educa??o B?sica. As situa??es?problema, inseridas no Produto Educacional, surgiram das interpreta??es dos conhecimentos matem?ticos, tomando como ponto de partida as compras realizadas pelos feirantes junto aos fornecedores at? as vendas destas mercadorias aos clientes na feira livre. Nesse contexto sociocultural nota-se ideias matem?ticas presentes, pois os feirantes fazem uso de um tipo de matem?tica espec?fica para solucionar seus problemas, inerentes nas compras e nas vendas: ao passar o troco e ao escolher a melhor ferramenta para quantificar as mercadorias, sem utilizar instrumentos aferidos, como a balan?a anal?gica ou digital. O Produto Educacional consiste em uma proposta alternativa para o processo de ensino?aprendizagem em Matem?tica, na inten??o de promover a amplia??o das habilidades voltadas para o c?lculo estimativo e a apropria??o dos conceitos matem?ticos aplicados em diversas situa??es, como tamb?m, nas outras ?reas do conhecimento al?m de ser, de fato, uma proposta para que os docentes implementem a??es did?ticos-pedag?gicas em sala de aula em Matem?tica. / This paper aims to analyze evidences of mathematical knowledge implicit in commercial operations of three market stallholders, located in Nova Natal Housing Complex, at Natal/RN. To achieve this goal, it was searched for theoretical support in the views of D'Ambrosio (2002) on Ethnomathematics, in the official documents? proposal, as well as in qualitative research. In the empirical part, it was used Ethnography procedures, such as diary, semi-structured interviews and participant observation. Based on the collected data?s analysis, it was elaborated an Activity Book as a proposal to support the process of teaching and learning in mathematics, guided by assumptions of teaching-learning-assessment methodology through the Solving Problem, based on the concepts of Onuchic & Allevato (2009) who assisted in the establishment of the Educational Product to the level of Basic Education. The problem-situations, inserted in the Product Educational, emerged from the interpretations of mathematical knowledge, has as a starting point from the purchases made by market stallholders for suppliers until the sales of these suppliers by the stallholders to the clients on the open market. In this sociocultural context, it can be noted the presence of mathematical ideas, since the stallholders make use of a specific type of mathematics to solve their inherent problems, on purchasing and sales: passing the change, choose the best tool to quantify the earnings, without using calibrated instruments as analog or digital scale. The Educational Product consists of an alternative proposal for the mathematical process of teaching and learning, intending to promote the application of abilities geared to estimated calculation, appropriation of mathematical concepts applied in different situations, as well as in other knowledge areas, besides it is, in fact, a proposal for the teachers to implement educational and pedagogical actions in the classroom.
